Functional Diagram
General Description
The HMC291 is a broadband 2 - bit positive control
GaAs IC digital attenuator in a 6 lead SOT26 sur-
face mount plastic package. Covering 0.7 to 4 GHz,
the insertion loss is typically less than 0.7 to 1.3 dB.
The attenuator bit values are 4 (LSB) and 8 dB for a
total attenuation of 12 dB. Accuracy is excellent at ±
0.2 dB typical with an IIP3 of up to +54 dBm. Two bit
control voltage inputs, toggled between 0 and +3 to
+5 volts, are used to select each attenuation state at
less than 50 uA each. A single Vdd bias of +3 to +5
volts applied through an external 5K Ohm resistor is
required.
Electrical Specifications,
TA = +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated)

* R2 = R3 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm
impedance while the package ground leads should be connected directly to the ground plane similar to that shown.
A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit
board as shown is available from Hittite Microwave Corporation upon request.
